Final answer:
Kevin rides 4 meters in 1 second.
Step-by-step explanation:
To find how far Kevin rides in 1 second, we can use the given information: he rides 48 meters in 12 seconds.
We can set up a proportion to solve for x, the distance he rides in 1 second:
48 meters / 12 seconds = x meters / 1 second
Cross-multiplying gives us: 12x = 48
Dividing both sides by 12, we find that x = 4 meters.
Therefore, Kevin rides 4 meters in 1 second.
